| Summary: | 博士 === 國立臺灣大學 === 化學系 === 85 === The acetone extract of twigs of the Taxus mairei was concentrated by
distillation.The residue was purified on column chromatography、flash column
chromatography、high performance liquid chromatography and recrystallized to
afford one hundred twenty three compounds.We distributed these compounds into
seven types.The first is taxane typediterpenoids; the second is the third is
diterpenoids; lignans; the fourth is flavonoids; the fifth is steroids; the
sixth is aromatic type; the seventh is other types compounds.These compounds
contain twenty seven new compounds.Their structures were determined by
spectral methods.
